It can be donated to any person, and it is universally accepted.
o
because it have no antigen.
O negative is the universal donor.
Universal recipient
O plus is called universal blood donor. Because O plus blood has anti A and anti B antibody. So it will not react with any blood group.
O+ :is a universal donor
The universal blood donor type is O negative and it is considered a universal donor due to it's not having any A or B antigens. It is better because that blood will be more useful to health care staff as they can give it to anyone without having to worry about the threat of transfusion reaction.
A universal donor (blood type O) has blood cells with no marker proteins that another body can not reject. Blood type AB, the universal receiver has all the marker proteins, so it can identify blood of any other type as its own.
compadibility with other blood types
Yes, A person having O +ve blood group is universal donor
AB+ is the universal receiver. O - is the universal donor.
O negative is the universal donor because when O+ve blood group is transfused to -ve blood group recipient, antibodies are produced which causes hemolysis of Rh +ve labelled blood cells. When O-ve blood is transfused to Rh +ve recipient, no antibodies are produced as donor blood has no Rh factor present on blood cells, so no transfusion reaction occurs. Thus, O -ve is universal donor.
